Tayutama -Kiss on my Deity-

Yuri Mito is a student at Sosei Academy and the only son of the Yachimata shrine's caretaker. The shrine is associated with Tayutayu-sama, a deity said to have once protected the region, though such figures, known as Tayutai, have long since vanished. During an exploration of the school grounds, Mito and his classmates find a relic marked with strange symbols. Shortly after, at the start of the new academic year, a mysterious girl named Mashiro appears. She is connected in some way to both the relic and the legend of Tayutayu-sama.
